(接上期)重新换装宝马BMWⅥ发动机后的ANT-6原型机于1931年4月29日再次试飞,相应的国家测试在1931年5月至8月完成,期间该机没有出现什么大的毛病,而特别要提及的是其失速性能非常令人满意(对于新手来说,这是个好消息)。在此期间,唯一对这架ANT-6原型机进行的再次改进,是将传统的单轮起落架改为了颇具特色的前后双轮式。这当中还有一个小插曲,当年7月(1931年),斯大林对ANT-6原型机进行了视察,并当既要求飞机升空进行表演,不凑巧的是该机的飞机员当时并不在场,工厂领导只得找来两名TB-1飞行员临时应急。所幸ANT-6操纵特性与TB-1差别不大,所以飞行表演进行的算是完美,斯
(Continued) The ANT-6 prototype after the BMW BMW VI engine was re-tested on April 29, 1931, and the corresponding national test was completed in May-August 1931, during which time the machine did not show any major problems , With special mention being made of the very satisfactory stalling performance (which is good news for beginners). In the meantime, the only improvement on the ANT-6 prototype was the conversion of a conventional single-wheel undercarriage into a distinctive two-wheeled front and rear wheels. There was also an episode in July of that year (1931) when Stalin inspected the ANT-6 prototype and, while demanding that the aircraft take off to perform, it was unfortunate that the aircraft’s pilot was not present , The factory leader had to find two TB-1 pilots temporarily in emergency. Fortunately, the operating characteristics of ANT-6 and TB-1 is not very different, so the flight performance is perfect, Sri Lanka
